Utilizing blockchain technology to create digital battery passports involves recording detailed information about a battery’s entire lifecycle, from raw material sourcing and manufacturing to usage and end-of-life recycling. This immutable and transparent ledger allows stakeholders, including manufacturers, regulators, and consumers, to access accurate data regarding battery composition, performance, and handling. Such traceability supports adherence to regulatory standards, promotes responsible recycling practices, and aids in assessing environmental impacts, thereby advancing sustainability and circular economy initiatives. The study “Digital Battery Passports to Enable Circular and Sustainable Value Chains: Conceptualization and Use Cases” explores how digital battery passports can enhance sustainability and circularity within battery value chains. It emphasizes that these passports serve as valuable data sources, enabling better tracking of battery materials and facilitating compliance with environmental regulations.
